JOHN SIMMERMAN, or DAYTON, OHIO.

STREET-RAILWAY SWITCH.

SPECIFICATION forming part of Letters Patent N0. 677,889, dated July 9, 1901.

Application filed November 3,1900. Serial No. 35,316. (No model.)

To all whmn it may concern:

Beit known that I, JOHN SIMMERMAN, acitizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Street Railway Switches; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. reference being had to the accompany ing drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in mechanism for operating a switch tongue from the platform of a car, having more particular reference to street-railway service.

The object of my invention is to construct mechanism for switching the switch-tongue, which may be placed on any of the switches now in use and which possesses the novel features hereinafter described and claimed.

Preceding a detail description of my invention reference is made to the accompanying drawings, of which- Figure l is a top plan view showing my switch-shifting mechanism located on both sides of a frog. Fig. 2 is a partial longitudinal vertical section through an end of a car, showing the switch-shifting mechanism. Fig. 3 is a sectional view on the line a; m of Fig. 1.

Fig. 4: is an elevation of an end of the shifting bar or lever.

The switch-tongue l is pivoted at 2 to the frog in the usual manner and is movable to direct the car on either the straight track A or the switch-track B. The mechanism for shifting the tongue in either position consists of a spring-bar 3,. which is rigidly attached at one end 4 to a side plate 5 of the casing and extends across the space between the inner wall 5 and the outer wall 6 of said casing. One end of said spring 3 terminates in a straight portion 7, which lies parallel with the outer wall 6 of the casing. 8 designates a pin which is secured to the end 7 of said spring-bar 3 and is movable through an opening 9 in said side wall 5 and opening 9 in the frog and in contact with the switch-tongue 1, whereby said tongue is moved. After the spring-bar 3 is relieved from contact with the operating-lever the said bar will withdraw the pin 8 from contact with the switch-tongue and the said bar and pin will assume their normal positions, as shown in Fig. 1.

The movement of the pin and spring-bar, it will be seen, is lateral and is effected by the switch-lever 10, which has a downwardprojecting blade 11, which enters the slot 12 in the top of the casing in which the springbar and pin are inclosed. Further reference will be made to this shifting-lever. The casing in which the mechanism is inclosed is shown in Fig. 1. Portions of the top on each side of the slot 12 are broken away to show said mechanism. This casing consists of an inner side 5 and an outer side 6, with top por tions 13 and 14, which project over the top and provide the slot or opening 12, in whichthe end 11 of the lever projects. This slot 12,it will be seen, is in a position to guide the'blade 11 of the switch-lever into contact with the outer side of the spring-bar 3 about midway of said bar. The entrance of the slot 12, as shown in Fig. 2, is provided with a tapering wall 15, which enables the end 11 of the oper ating-lever to have a proper entrance to the slot 12; also, a tapering Wall 16, which allows the said lever to have a proper exit from said slot. These tapering walls 15 and 16 are provided in the parts 17 and 18, which form the ends of the casing. The casing'thus made up, including the spring-bar 3 and the pin 8, is an attachment which may be applied to any frog by bolting the wall 5 to the frog or to a guard-rail and providing the frog or guard-rail with a suitable opening 9, through which the pin may pass in its operations to make contact with the switch-tongue 1, as shown in Fig. 1. The switch-shifting device is located on the outer and inner side of the frog, which enables the switch-tongue to be shifted in the two directions. The shifting-lever 10 is fulcrumed at 19 to the forward end of the cartruck and in a position to allow the straight surface 20 to ride upon the frog or car-rail while the blade or projection 11 enters the slot 12 a suitable distance. The shank of said. lever is pivoted to an uprightoperatinglever 21, which projects through an opening 22 in the platform of the car within reach of the motorman, who may operate said lever to lower it in a position for the blade 11 to enter said slot 12 and the straight portion 20 to ride on one side of said slot.

Having described my invention, I claim 1. In a switch shifting mechanism, the combination with a casing secured on each side of a switch-tongue, each of said casings having an opening in its inner Wall and a longitudinal slot in the top thereof with tapering walls at the ingress and egress of said slot, of a resilient bar secured at one end to the inner wall of each casing and projecting across said slot from the inner to the outer" walls of the casing, a laterally-movable pin secured to said bar and movable in and out of the opening in the inner wall of said casings to move the switch-tongue in two positions, and means for operating said resilient bar to move the switch-tongue in one position.

2. A switch-shifting mechanism comprising a casing secured on each side of a switchtongue, each of said casings having an opening in its inner walland a longitudinal slot in the top thereof with tapering walls at the ingress and egress of said slot, a resilient bar secured at one end to the inner .wall of each casing and projecting across said slot from the inner to the outer walls of each casing, a laterally-movable pin secured to said bar and movable in and out of the opening in the inner wall of said casings to move the switchtongue in two positions, an operating-lever havinga projecting portion 11 which is adapted to enter the longitudinal slot in the casings and to engage the resilient bar to move the pin in contact with the switch-tongue, the said projecting portion riding on tapering Walls at each end of the slot, substan tially as shown and described. I

In testimony whereof I aflix my signature in presence of two Witnesses.
